Question CKEditor problem?

Excuse me. I'll be more specific: the "image" button in the BBcode editor does not work. This statement is true for creating a new post or editing an old post.
Strangely, I did not see any errors in the console.

I remember you once wrote something about the template Purity. So I tested it with that and found that there is a conflict with the BBCode editor. Unfortunately, I can't find a solution.

You are very kind, thank you, rich. I suspected it, but didn't check it out. But you didn't have to waste your time on it. Purity III is a pain, my Purity css hacks file is over 500 lines long.  It doesn't work otherwise.
Joomlart has given me a nasty gift. You'd be surprised, but the information on List of supported 3rd extensions page is a fraud on users. Purity III doesn't support Kunena 6 at all (it took me a lot of effort to make this template work with Kunena 5). But it's impossible to reconcile Bootstrap 5 with the current version of Purity, this is nonsense.

When I upgrade to Joomla 4 and Kunena 6, I will be forced to bind Cassiopeia styles to the forum. Despite the fact that I chose Purity because of Joomlart declared support for Joomla 4. A lot of effort spent on Purity, I do not want to give it up now. Although Joomlart scam made a very unpleasant impression.

Try t wit the t4_bs5_blank template from JoomlArt, it has fewer errors ().

Sure, I'll give it a try.
